JS Help With Local Scope & Functions

I am trying to do this code challenge on Free Code Camp, and it seems to me like I am doing everything right but it isn't working. Any help is appreciated

Here are the directions:

Declare a local variable myVar inside myLocalScope. Run the tests and then follow the instructions commented out in the editor.

function myLocalScope() {
  var myVar = 'use strict';
  console.log(myVar);
}
myLocalScope();

// Run and check the console
// myVar is not defined outside of myLocalScope

console.log(myVar);

// Now remove the console log line to pass the test

I get that it is trying to show me that a local variable can't be called outside of a function. Nothing changes though when I remove the console.log(myVar) which tries to call the local variable that doesn't exist globally.

If you removed the second console call then you don't seem to be doing anything wrong. I decided to try the test myself and using your code with the console call removed:

function myLocalScope() {
  var myVar = 'use strict';
  console.log(myVar);
}
myLocalScope();

It did seem to pass the test fine, maybe it was just a temporary bug?

It seemed to be a bug. It let me pass this time.
